Doty would have the operation later this week and would not return until spring practice.
Doty missed the first two games this season due to the injury when someone stepped on his foot at practice in August.
The sophomore came in for an injured Noland vs. No. 1 Georgia in Week 3, then started the next four games. With South Carolina trailing 20-14, Noland subbed in for Doty on the final drive and led a 75-yard touchdown drive in the Gamecocks' 21-20 victory Saturday night.
Beamer said Doty was in good spirits, attending practice on Sunday and taking part in offensive meetings Tuesday.
"Don't think it's anything that's going to affect him long term." Beamer said.
Doty has completed 86 of 143 passes for 975 yards with five touchdowns and three interceptions.
